Across The Universe - The dinosaur-murdering asteroid maybe also triggered an underwater volcano meltdown

The dinosaur-murdering asteroid maybe also triggered an underwater volcano meltdown:

The cataclysmic asteroid that wiped out the dinosaurs might have also triggered massive volcanic eruptions deep beneath the ocean, new research says. It’s yet another way the extraterrestrial impact could have killed off more than 70 percent of life on Earth — that is, if the timing isn’t just a coincidence.

Roughly 66 million years ago, a 6-mile-wide asteroid crashed into Mexico’s Yucatán Peninsula — causing a massive, worldwide earthquake. That Earth-shaking impact might have made underwater volcanoes spit up magma even more ferociously than usual, according to a study published today in the journal Science Advances. These events might have added to the asteroid’s apocalyptic aftershocks — which include wildfires, global cooling, and...
